It should "just work". It could be that your TERM environment
variable is not being exported. In the :shell shell, execute

echo $TERM

If that doesn't show anything, then add

export TERM

to your ~/.bashrc or ~/.bash_profile. I would put it in
~/.bash_profile, but the fashion these days seems to be to put
everything into ~/.bashrc.

The solution I use is to put this in my ~/.bashrc:

if [ "$VIM" ] && [ "$TERM" = "dumb" ]
then
# For gvim's monochromatic :shell
PS1='\n\u@\h \w\n\$ '
unalias ls
unalias grep
fi
